ANSC*6370 QG and Animal Models
Fall 03 - Quiz 10

1.

Non-Additive Genetic Model

(a)

How might you simulate dominance genetic effects?

(b)

What assumption is necessary for the non-additive genetic model that was discussed in class?

2.

Maternal Effects Model

(a)

If $\sigma^{2}_{a}=10$, $\sigma^{2}_{m}=4$, $\sigma_{am}=-2$, $\sigma^{2}_{mpe}=25$, and $\sigma^{2}_{e}=100$, then calculate the appropriate k-values for use in the mixed model equations for the maternal genetics effect model.

(b)

Do sires receive an estimated breeding value for maternal genetic effects? The answer is Yes - but tell me how this happens.
